What is the Japanese Train Set?

It is a vehicle set for Transport Tycoon Deluxe with TTDPatch or for OpenTTD. It depicts the railroading equipment of Japan, from interwar steam to the latest Shinkansen bullet trains.


Japan is mostly temperate, but the northern island of Hokkaido has weather roughly similar to that of Northern Europe or New England. Thus, the Japanese Train Set operates in the Temperate and Arctic climates. Japan does not have rail operations in the tropics (Okinawa island is somewhat tropical, but it is too small for much of a rail system), so the Japanese Train Set does not appear in the Tropical climate.

The Japanese Train Set is part of the Japan Set which consists of the following GRF files, available from the Japan Set homepage:

Installation and settings for TTD Patch

For general information on how to use GRF files in TTDPatch, read the TTD Patch manual.

You will need TTDPatch version 2.5 beta 9 (or higher), available here. For full features, we recommend that you use the latest nightly version. The Japanese Train Set is available in a DOS version ("jptrainsd.grf") and a Windows version ("jptrainsw.grf"). Simply copy the grf file into the "newgrf" folder inside your TTD main folder and add the entry "newgrf/jptrains[d/w].grf" (with the "d" or "w" depending on whether you are using the DOS or Windows version of TTD) to your "newgrf[w].cfg" file.

You need to set the following variables in your ttdpatch.cfg file:

You should also enable the "realistic model" of train acceleration to get full benefit from the different engines in the set, i.e. you should include in your ttdpatch.cfg file the lines: (x is for road vehicles and should be set to a value of 0 to 3.)
mountains 333x
curves 333x

Installation and settings for Open TTD

For general information on how to use GRF files in OpenTTD, read the OpenTTD manual.

You will need OpenTTD 0.7.0 (or higher) for full features. If you have downloaded the Japanese Train Set from the Japan Set homepage, simply copy the grf file into the "data" folder inside your OpenTTD folder. Alternatively, you can use OpenTTD's online content service, as described here. To use the Japanese Train Set in a new game, you only have to add it under NewGRF Settings on the title screen.

It is not recommended to add the Japanese Train Set to an existing savegame (unless that savegame was using an older version of the Japanese Train Set already). If you wish to do so anyway, you can activate the Japanese Train Set under NewGRF Settings in the Options menu. Note that this will most likely make your existing trains unusable, since many wagons will be changed into locomotives and vice versa.

If you have an older version of the Japanese Train Set installed, removing the old file and adding the new one will make all your old savegames use the new version. (OpenTTD will display a warning upon opening such savegames though). Upgrading old savegames in this way might work, but a few glitches are to be expected.

You should change the following settings under Advanced Settings on the title screen:

GRF parameters

GRF parameters can be used to customize various aspects of the Japanese Train Set. (Information on how to use GRF parameters: in TTDPatch; in OpenTTD).

The following parameters are avaible (default values in bold print):

1st Parameter: Track graphics

Important note: This setting affects the graphics only. So for example the value 2 does not mean that Shinkansen trains can run on normal tracks.

In TTDPatch, Shinkansen tracks will replace either monrail or maglev depending on the setting of the unified maglev switch.
Narrow gauge and Shinkansen track graphics are included for both the Japanese landscape and for the default TTD graphics (including proper road crossings).

2nd Parameter: Mail cars

Note that mail car sprites are currently unavailable for some multiple unit trains. However, this does not affect the possibility to attach mail cars to all trains.

3rd Parameter: Costs

Add 8 to these values to switch running costs for wagons off in OpenTTD (automatic in TTDPatch). Note that the value of the 4th Parameter will also affect running costs for wagons.

4th Parameter: Capacities and loading times.

There are three different classes of passenger trains in the Japanese Train Set (see also List of vehicles below). The seating capacities of passenger cars can be changed via parameter as follows:

Par. 4 Passenger Trains Express Trains Commuter Trains Shinkansen Trains
0 (default) 50 40 60 50
10 65 50 75 65
20 75 60 90 75
30 90 70 105 90

Important Note: Wagon running costs are increased along with the capacities.

The parameter also controls the loading and unloading times of trains, by adding the following values:

Commuter trains will load and unload about twice as fast as express trains, and standard trains are somewhere in between. The load amount will scale with the capacities so that loading times will remain roughly the same when capacities are changed. The slow setting corresponds approximately to the TTD default loading times.

Examples: If you want the lowest wagon capacities but fast loading, set the 4th parameter to 2. For the second lowest capacities and normal loading the value is 11. For the highest capacities and slow loading it is 30.

Compatibility with other GRF files

The Japanese Train Set is designed to be used together with the other GRF files in the Japan Set listed above. It is not intended to coexist with any other train set. (In OpenTTD, it is technically possible to use the Japanese Train Set along with other train sets. However, this will most likely affect purchase and running costs in some or all of these train sets (including the Japanese Train Set), and might produce all kinds of other problems. It is therefore not recommended, unless you really know what you are doing.)

GRF files relating to other vehicles such as ships, road vehicles, and aircraft, as well as stations, will not be affected or harmed by the jptrains[d/w].grf file. However, since the Japanese Train Set overrides the maglev/monorail tracks with Shinkansen tracks, it is incompatible with any grf that changes roads, rail tracks or landscape graphics, except the Japanese Landscape Set. Using the Japanese Train Set together with such GRFs will likely cause more or less severe graphical inconsistencies, but will usually not affect gameplay.

The Japanese Train Set is compatible with the Extended Cargo Scheme and can therefore be used with New Cargo GRFs such as Pikka's Basic Industries or George's ECS vectors. All cargos in the current versions (April 2009) of these two sets can be transported by the freight cars in the Japanese Train Set. However, this cannot be guaranteed for all future versions, nor for other New Cargo GRFs.

Playing the Japanese Train Set

Narrow gauge tracks

The main Japanese rail system is not standard gauge but narrow gauge (more precisely 1067mm "Cape gauge"). By default, the Japanese Train Set will alter the rail graphics to reflect this (see Parameter settings). Apart from that, the normal and electrified trains and tracks in the set operate just as they do in any other set for TTDPatch/OpenTTD. However, just as in reality, the use of narrow gauge tracks means that ordinary trains cannot travel faster than 130 kph (80 mph) (some modern tilting trains can go up to 160 kph). This was one of the main motivations for the construction of the Shinkansen network.

Multiple unit trains

Most Japanese passenger trains from 1950 onwards are multiple unit trains. All cars placed in the train provide motive power just as if they were all locomotives. Thus a long train will have the same performance as a short train. The multiple unit trains can only be used for passenger and mail service (except the M250).

Many multiple unit trains have different types of cars (forward and rear driving cabs, cars with pantographs, and sometimes restaurant cars and other graphical variations). Some trains will look odd if they are used with the "wrong" number of cars. (For example, the 72 Series EMU should always have a total number of cars that is divisible by four. If used with five cars, the last two cars will both be backward facing driving cabs.) A future version of this readme will feature a train guide with the proper configurations for each train. Which configurations will look good (or bad), should be quite obvious from the depot view.

Livery refits

Many trains, in particular multiple unit trains, come in several different liveries. Use the refit button to choose the desired livery (as you would with different cargos for freight trains.) Some liveries only become available from a certain date onwards. The number of different livery options and the times at which they become available are stated in the purchase menu.

Brake Vans

Japanese freight trains, like British ones, often have a brake van at the rear of the train. On a shorter train, there might be only a brakeman's cabin provided on an otherwise ordinary freight car. The Japanese Train Set offers brake vans for purchase; they carry no cargo, but are required for freight trains without contiunous braking. From 1950 onwards, the second generation of freight cars will start to appear. These are equipped with continuous brakes, making brake vans unneccessary for new trains around 1970.

Shinkansen Trains

The Shinkansen bullet train network is standard gauge and is entirely separate from the rest of the Japanese rail system (except for sharing stations.) To reflect this, the Japanese Train Set uses the maglev (or monorail) track type as the Shinkansen system. The set includes graphics for Shinkansen tracks that look different from monorail, maglev, or normal train track. Shinkansen trains cannot use any other kind of track, nor can any non-Shinkansen trains use Shinkansen tracks. Shinkansen trains do not carry cargo of any kind, just passengers and mail. To fit into TTD gameplay better, the set allows mail cars also to be included in a Shinkansen train. Shinkansen trains can share a train station with normal trains, by replacing some of the existing tracks in the station with Shinkansen tracks, or by adding additional tracks to the station of the Shinkansen type. Both methods were used when the Shinkansen system was built.

List of vehicles

train list

The following tables give the details of each type of locomotive and wagon with the following information:

The recommended usage of each engine or multiple unit is also displayed in the purchase menu:

P Passengers Light and usually cheap to run. Locomotives mostly lack the power, speed, or tractive effort for express passenger or freight service.
EP Express passengers Fast and powerful. Steam locomotives usually lack the tractive effort needed for freight service. Trains have lower capacity and are somewhat more expensive to run, but are faster. Shinkansen trains are much faster but also a lot more expensive to operate.
C Commuter trains More expensive to run than ordinary passenger trains but with higher capacity and shorter loading times and therefore suitable for frequent stop and go.
LF/P Light freight or passengers Light engines for universal use.
HF/P HF/EP Heavy freight and (express) passengers Heavy engines for universal use. Beware that running costs for passenger trains may be high, especially with short trains.
HF Heavy freight Powerful and high tractive effort. Mostly lack the speed for express passenger service.

Start Year/End Year refers to the period in which the engine can be purchased. Both give only estimates: The start year is delayed by a random amount of time (up to about two years) while the end year may depend on game settings.
Tractive effort is explained below.
Veh. ID is a purely TTD internal information for GRF developers and totally irrelevant for gameplay.

(*) Capacities of passenger and mail cars depend on the value of the 4th parameter

Wagons can be refitted to the cargos shown in the table above but train refitting is only available at a consist level. Therefore, the refitting list will display all the possible cargos that at least some wagons in the train can be refitted to. If you wish to refit only some wagons to a specific cargo, you should first remove them from the train before carrying out the refitting. Obviously, if one type of wagon in the train cannot be refitted to a certain cargo then it will not be refitted that way if you choose it in the list.

Tractive Effort

Both TTDPatch and OpenTTD support a much more realistic way of modeling locomotive power than the original TTD, which measured power simply by a horsepower rating. The full horsepower was assumed to be available at all times, and all speeds. In reality, locomotive dynamics are rather more complicated, because steel wheels on steel rails do not offer that much friction and hence traction. The weight of the locomotive that is on the driving wheels has a major influence on the effective ability of the locomotive to transfer its power to the track. It does not matter how much HP a loco has if it is just spinning its wheels because the train is too heavy; and steam locomotives in particular are very subject to this problem.

The tractive effort parameter takes this into consideration. It is displayed in the New Vehicle Purchase window, and has a major effect on vehicle performance. A freight locomotive has to have a fairly large tractive effort in order to get the train started at all. To reach a high speed, a high horsepower is helpful, but the TE is really more important. For passenger trains, which are lighter, the TE is less important and the HP more, because the HP affects the maximum speed the train can reach. TE is particularly important if the train needs to climb mountains, and essential if the train will have to start from a full stop on a mountain. If the train starts up a mountain going at full speed, the momentum it has already acquired will help it up the hill; but if the train has to start up the hill from a dead stop, it is all based on the TE of the loco. That is why some locomotives with very high horsepowers do poorly in freight service, and others with low HP do well.

The Japanese Train Set is designed for realism in both tractive effort and horsepower. Each locomotive has its niche, and to find it, you need to carefully consider the tractive effort as well as the other parameters.

Known bugs

Please report any bugs in the release thread, unless they are already listed here:

These issues are due to current limitations in OpenTTD. We hope that they can addressed in future releases.


The Japanese Train Set was developed by an international team of members of the Transport Tycoon Forums (administered by Owen Rudge) and includes some elements previously developed by others. If you believe your work has been used and you are not properly credited, please post your concern in the development thread for immediate attention. Second-hand complaints will be disregarded; specific complaints with evidence will be rectified as soon as possible. Please bear in mind that the TTD vehicle sprites are very small, and as such there is unavoidable similarity between similar vehicles.
